(2011)<p>Anyway, I like this sentence a lot:<p>&gt; One useful point from that discussion is that the static vsyscall page is not, in fact, a security vulnerability; it&#x27;s simply a resource which can make it easier for an attacker to exploit a vulnerability elsewhere in the system.<p>One thing that&#x27;s always irritated me is that dubious &quot;hardening&quot; changes like this one get lumped together with fixes for actual vulnerabilities, and then both get labeled as &quot;security&quot;.
